leaf-rolling cricket

leaf-rolling cricket, (subfamily Gryllacridinae), any of a group of raspy crickets characterized by its nest formed of a leaf that is rolled and tied with silk. Leaf-rolling crickets are wingless or nearly wingless, have long cerci and antennae, and appear somewhat humpbacked. They have no sound-producing or hearing organs and do not jump. Like other members of the family Gryllacrididae, leaf-rolling crickets are nocturnal. They spend the day hidden within the rolled leaf, emerging at night to feed on aphids. The Carolina leaf roller (Camptonotus carolinensis) is about 15 mm (0.5 inch) long and is the only North American member.
